Do you know "XENON-80" ?

Do you see more ?
Please solve my question
I had found *experimentally* that
there are difference about the handling of "CTS"
in Intel i8251A and NEC uPD8251A.
if "CTS (Clear To Send)" negation is occurred while sending,
Intel i8251A *re*-send the data automatically *again*
after next "CTS" assertion.
Is this specification of Intel i8251A ?
Who is he ?
